Headless E-Commerce Case Study
Custom Gift Hub — Zero-License Headless E-Commerce with Vendure & Next.js
Ultra-low cost, high-speed headless e-commerce store engineered using Vendure (TypeScript/GraphQL) backend and Next.js frontend on 100% free-tier developer tools, built to effortlessly scale from 10 to 5,000+ SKUs.
Challenge
The business problem
Custom Gift Hub, a personalized gifting and custom merchandise brand in India, was caught in the classic e-commerce dilemma. Hosted SaaS platforms like Shopify charged hefty monthly subscriptions ($39-$399/mo) plus 2% transaction fees and expensive app addons for photo uploads and customization. Conversely, legacy WooCommerce on shared hosting was slow, bloated with 30+ plugins, and prone to database crashes during festive traffic spikes. They needed an enterprise-grade headless architecture with sub-second page loads, photo upload capabilities, and ₹0 monthly software license overhead.
"Curve Metrics delivered what seemed impossible: an enterprise headless e-commerce experience that runs on zero monthly tool fees. Our store is faster than any major brand, our customers love the WhatsApp updates, and we saved lakhs in platform fees."
